at the base, acute, denticulate along the longer edge and about the 

 apex; stipules subulate, the under pair thrice the length of the upper. 

 Involucres minute, nearly sessile by their narrowing bases, pyriform, 

 stiff pilose especially above; lobes mere bundles of ciliae; glands as in 

 dioica; appendages deep red, the upper pair 1.5 x .8 mm., narrowing to 

 a blunt apex, margins irregularly repand-dentate, the lower pair fla- 

 bellate. Male flower pedicels glabrous; female stiff-pilose especially 

 above; ovary stiff-pilose, styles united at the lower third, bifurcate 

 one-quarter their length into recurved stigmas; capsule setaceous-pilose, 

 cocci rounded; seed triangular-ovoid, pinkish, .90 x .60 mm., acute at 

 the apex; angles slightly corrugate; facets plane; ridges broadly convex, 

 sulci 5, narrowed to a mere line.

Prostrate, spreading from a slender, elongated, ligneous root; stems 

 many from the base, compressed, pilose above and especially on the mar- 

 gins, glabrous beneath; branches profuse, divergent, internodes short, 

 4-6 mm.; branchlets alternate. Inflorescence solitary in the upper 

 leaf axils of the branchlets and tips of the branches. Leaves ovate, 

 5 x 3 to 7 x 4 mm., glabrous on both surfaces, unequally cordate, more 

 or less acute, slightly crenate-dentate; petioles i mm. or less, mostly 

 glabrous; stipules slender subulate-aristate, mostly glabrous, the upper 

 somewhat exceeding the petioles, the under twice their length. In- 

 volucres turbinate-campanulate, the outer surface minutely pilose, the 

 inner densely woolly; lobes flabellate, ciliate; glands transversely oval, 

 cupped, somewhat less than half the size of the appendages; appendages 

 white, the larger (1.2 x .3 mm.) crenate-margined, the smaller (.6 x .2 

 mm.) erose-dentate; pedicels of the male flowers ligulate, glabrous, those 

 of the female pilose above; ovary pilose; style trifid to the base, the 

 branches bifid one-third their length. Capsule pyriform, pilose, cocci 

 rounded; seed triangular-ovoid, .90 x .60 mm., pinkish; apex acute, the 

 dorsal angle most prominent, facets plane, ridges rather broad and 

 rounded, sulci 5, shallow but well defined, seed-coat minutely pitted.
